'Y Specification forming'partof Letters Patent No. 36,4 I7, dated-'September 9,1862.

` To all whom' it may concem..

Be it knownv that I, C. B. MATTHEWS, of Oquawka, in the county of Henderson Iand State of Illinois, have invented certaiif'new and useful Improvements in llLamp-Burners; and I do hereby declare that the following is a full, clear, and exact deseri ption of the same,

reference beinghad to the aecompanying'drawings, making aj part'of this specilieation, in which- Figure 1 is a vertical central section of my invention,`taken in 'the linem m, Fig. 2. Fig.

'2 is a plan or top view of my' invention with the cone partially biscctcd or broken away;y

Fig. 3, a detached perspective view of a portion ot' thesame.

Similar letters of reference indicate correl sponding parts in the several figures.

- 'ro @name Atime ski-ned 'n the are to funy understand and construct my invention, I will proceed to describe it.

, A represents alamp top or burner, B the wick-tube, and C the'cone orfdeflector. 'Ihesel parts may be constructed in the usual way,

are bent so as to cross earch other and'terminate in eyes c c, which may be readily grasped "by'ithe finger and thumb and pressed toward each other for the purpose of expanding the jaws b b, as shown in red in Eig.-2.

'. The clampD 1s secured to' the 1amptop A by soldering to ita projection, d, underneath the .coil-spring a, and the clamp, if desired, may be constructed of two pieces of wire, each piece containing a jaw, b, and one-half of the spring a, both pieces-being connected to the lamp-top at the samep'oint. The elasticity -of the-'spring a causes the jaws b b to tit over theflan'ge eat the base of the chimney E7 and f thereby secure the latter to the lamp top or burner,` the chimney -being detached from the burner by pressing the disengaged ends of the jaws b b toward each other, as previouslyexplained.

This device forms a very simple and eco nominal chimney -fasteningmone that may loe operated with the greatest facility, and

jaws themselves, ad mit of the chimney expand-l ing 'freely as it becomes .heated under the action of the flame, the chimney at theqsame that it cannot be casuallydetached.

edge of a hole, f, in the-bottom of the burner and the upper end nearly or quite in contact with the side of the' burner. vThisprojection] into the fountain of the lamp. Infillfinglthe movedfror'n thevburner. This filling attachnient is extremelyconvenient and saves a great taching the burner from the fountain and preventing the dropping of oil upon the lamp, which always occurs? to a greater 'or less extent even when the wick is drawn but partially out from the fountain'.

upper Hend of an elastic vbar, H, within the burner. The bar H is bent. or curved at its is formed at the inner end of a rod or bar, I, the outer part of which passes through the side of the burner, so that it may be'readily v grasped by the operator. The spring formed by the coils g has a ytendency to keep the fork G in contact with the Wick in tube B, and in' order to raise the wick the outer end of the raises the fork` G, and consequently the wick, the spring g keeping the fork in contact with the wick, but not causing it to press or bear against it very hard', an excessive pressure not being required. This arrangement-fit will be 4thicknesses--a result not attained by the ordinary toothed wheels placed on a shaft fitted in thickvwicks to be .compressed to such a degree as to prevent the free ascent of the oil and sometimes to rupture the wick-tube. It will be seen, however,.from the above description that the same en'dmay be attained by which will, owing to' the4 elasticity` ffthe spring a, together with the elasticity of the.l

.time being firmly secured' to the burner-,aso` n Within the burner A there isplacifane permanently secured -a curved scoop-like pro-A- jection, F, the lower,end of which is at the.

F serves as a guide or funnel to directthe'oil fountain the chimney E and cone C 'are redeal of trouble, obviating the necessity'of de- G representsa fork, which is attached tothe i lower end to form one or more coils, g, and issecnred to the wick-tube B at the bottom of the burner, as shown in Fig. 1. The fork G,

rod or bar I is depressed, and that movement seen, accommodates itself to wicks of differentfiXed bearings, and which frequently canse having 'the shaft of the toothed wheels fitted4 in a. springyas illustrated in Fig. 3, h-.represcntin'g the wheels, 'i the shaft, and j the spring,

one end of which may be attached to the burner and the shaft z' to theopposite end, the spring being bent in V form. The latter modification, however', is an equivalent of the first. f

J represents a {loam-,Which maybe con. s tructed of cork or othermaterial which will float on the surface of` theoil inthe fountaini.: This oat has a rod, K, attached to it,4 whih' passes upward into the burner A and indicates the height of the oil in lthe fountain; This indicator is an?` important feature o f the" invention when metal lamps'areemployed, as

it always showsvwhen the fountain requires to be replenished with oil.

Having. thus described my invention, what I claim as newfand desire' to secure hy'y Letters 1 Patent., is"- 1. The' arrangenientl 'of the lspring l1)',I'With the lamp-top A, cone C, and oh-im'ney E, inthe mannerjherein shown and described, so that the said spring will adj ust'itself both vertically "and laterally to the chimney and press lthe chimney Awith a yielding pressure in both direetionsr aliasl 'seb forth. i
